[Q] Partition SD Card (different than previous questions asked)

First off, to eliminate the flamers 1)I know you don't need to partition your SD Card (i've been running android on 2 SD cards for around a month now) 2)I know it won't make my device run any faster.
The question is though If i partition my memory card to have the 3 partitons: ext, linux swap, and fat32, will this mean that on the main part of the memory card that my windows mobile can see that i won't have all of the various folders that the Android OS creates (i.e: .android_secure, .bookmark_thumb1, rosie_scroll?
The reason i ask is i want to have my memory card as clean as possible so that within my windows mobile build that it is still very organized.
Thanks for any help you can offer. If you are going to reply simply to say use the search, I have, I've read and thank you very much, you can now move on to the next topic to type that.

I also have the same question.
How get clean memmory card from Android folders?
Or how to install Android in folder (sdcard/Android/all android folders)
Than my WM folders will use (sdcard/WM folders)

I second either of these as to keep my mem card tidy from all the android folders created and mixed up with my WM files.

Well since no one seems to know the answer or isn't willing to share, I am going to try doing this within the next two days and will report back on whether or not it works.

How would each OS know what partition belongs to it?

Nice to hear that! I think there is 2 ways:
with partition on sdcard
change Android install place to place in folder
Somone who build Android roms can try to change location where android install apps.

If you crate partition for linux (ext...) windows will not show, read and find it.Also WM will not read files on linux partition but I think that linux still will read both. Dono how it is on Android but in Ubuntu on PC it works.

SD partitioning works great!
This is how to create partitions on your SD card: http://forum.xda-developers.com/showthread.php?t=267475
I tried it - and it works. WinMo shows two storage cards - 'Storage Card' and 'Storage Card 2'. The first one is the Active partition - which is my Android partition.
When you are in WinMo and installing WinMo software, you are given the choice of where to install it - and it shows both storage cards. So in effect you can have all that is WinMo on one partition and all that is Android on another. Android is working nicely from its own partition.
I must say - this is the first time my Android is working sooooooo well. As well as my wife's HTC Desire device. It is a noticeable difference - the same Android build worked quite sluggishly before this exercise. It is either because I am using a freshly formatted partition, or because it has its own partition now.
My partitions were formatted with FAT32, 32KB unit allocation size. I am using ChuckyDroid ROM and currently testing this Android build Core_Droid_V.0.2.
Yeey ! " ... after action - satisfaction .. "

[Q] After reboot I need to format SD card to run Android - why?

I have 16 GB SD card (scan disk) and after I formatted (with card reader on windows XP) the card to FAT32, I run android successfully.
After reboot I started WM (Energy ROM) and when I try to run android again it stuck on boot screen (white screen with HTC in green).
I need to reformat the card again, copy the android folder again and then to run android again.
Is there a possibility to switch between Android & WM without formatting the card every time?

baby jesus doesn't love you anymore

At first, you posted in the wrong topic. This thread should be in Android General Section.
Second, try to format your card two or three times with this tool:
World Formatter
And read this:
Manual
Cheers

i'm joking i have no idea why that's happenning

I'm not sure why your having that problem, maybe cards can get worn after formatting so many times? Not sure, but I haven't formatted my card in over a month and have had WAY less problems than when I use to format it a few times a week.

I have 8gb card, but i never need format, just im copy Android folder to sd, and run Android.
i suggestion, you try another sd card, may be your card have a little problem.

but whatever is your problem is I love the "Baby Jesus" part .. LoL
now to topic -- as said earlier .. try with some other card u have... ur card may be faulty

And as said, I was also a "format-junkie" but I think it's better to just leave the card as it is. Mine works fine now, I haven't formatted since a month.

i had massive problems on my 16gb card but it all cleared up when i formatted using the format tool under windows mobile on the cell phone. i dont think it matters but im using miri's rom. if you want to know the exact verison of what rom im using let me know.

I just formatted the SD card in android and it worked fine, able to store everything on there and android recognizes it fine. maybe i got lucky

hi 96edwy
i've asked you on your youtube link but also on here if you don't mind
i have a working 8GB PNY micro sd card that has been reformated from 199mb capacity
i want my hd2 wm7 to recognise it so i can use it to store more conversations, applications and put music on
do you have any idea how i can achieve this?

If wp7 doesn't recognise it, maybe its not supported, there is a thread on here with the sd cards that are supported, have you checked if your sd card is supported?

Thanks for youtube video. I have 16gig that come with htc hd2 some people say it works flawless, but mine keep boot up to DFT and reboot cycle. Rarely I open it up and it will go to windows. So when you install windows phone 7 it will automatic copy file to SD card right?

May be WP7 doesnt support your SD Card. Check the supported SD Card list.

yes sorry to say your sd card is gone, all data is lost.
you can go back to wm6.6 by flashing a stock or custom rom, just boot into the tricolour screen and flash as you would any normal rom

Thanks God anyway
but when i try to flash custom Rom it gaves me connection error on the installation progress
why is that ?

I just mount SD card in MAGLDR then diskpart clean it then format it normally...

allow usb connection from your active sync

you need to allow usb connection from your active sync which is disabled in order to flash wp7

Thanks again
Hey Dude thanks for getting my card back very much appreciated, excellent tutorial

Manual with Command promt
1. Run command prompt with admin privileges
2. Type in diskpart
3. Type in "list disk" to find diskpart's designation for your flash drive
4. Assuming your flash drive is disk 1 type:
a. select disk 1
b. clean
c. create partition primary
d. select partition 1
e. active
f. format fs=fat32 quick
g. assign
h. exit

after runnng wm7, i still can format sdcard by using another android phone/nokia phone. And the sdcard is recognized when my phone is running android/wm7/wm6.5). But there are 2 weird problems that i can't solve:
1. cannot use SD formatter v.30 software to format my sdcard again. always get error message when the format process reaches 30-40%. Even if i pre format my sdcard by using another software(hard disck low level format, partition wizard) /phone( android phone, nokia, window 6.5 phone), SD formatter still can't format my sdcard.
2. cannot install any android SD builds. When the android boots, the screen show me " ... cannot find any logical sector..."

thanks!

i thought that was obvious tbh, it works exactly the same both ways, just easier to not take the sd card out your phone, plug it into an adapter then into a card reader, u eva thought people might not have a card reader??

[Q] The new 7720 ROM - Encrypted Card, What to do?

Hi,
I'm trying to keep up with the thread on the development forumm but theres to mach going on there.
Can someone please explain what's that they are saying that the rom is locking the sd card and the tonight there will be another rom?
What all this about? whats the difference between the current rom and the new one?
Thanks

it locks the sd card meaning the sd can no longer be used as a regular sd card and will only work on a windows phone 7 device

yeah, at the moment, you have two choices
use the V1 ROM and be able to upgrade your ROM, you can install android still, you can not upgrade to 7712 / 7720 AND have access to your SD card UNLESS you lock the SD card
the second choice is use V2 ROM, this will lock your SD card from the start and enable updates to be much easier
Locking the SD card means that it can not be used at all on another device, Currently there isnt any software that can format the protected portion of the card, some hardware devices can format it, Some Nokia phones, some camera
Locking is actually very useful unless you want android on the same SD card
If you do want to use Android as well then get a second SD card and pop it in when you want to use it.
WP7 its self CAN clear a protected SD card but it will keep it protected, so you can reflash new WP7 ROMS with protected SD cards without any issues at all, but it will always be protected unless you use a Nokia type device.

You can also format a locked card using your wm6.5 on hd2;-)

No, it cannot. It says it is damaged on my topaz.

A buggered up partition table can be fixed with a propper format which is what 99% of people say "fixes" a broken card.
However, a "Protected" Card can not be formatted in this way, im have a chat with the SD association at the moment to see whats what, so far it is a software limitation on the PC that is stopping us clearing that data, in short if someone writes a program to do it, it will do it, the question is how!

can you guys see the partition on a PC partition app but not modify it? Or can you not even see the partition?

if a SD card has been locked its essentially unreadable in anything but the device that it was locked in, if you plug a locked (protected) SD card in a PC it will be detected in device manager but windows will not beable to access it, the SD association is a bit vague in their replys but apparently some OSs are able to format a protected card, MS isnt one of them unless there is undocumented flags that can be used at the command prompt, the best bet is probably Linux, I hate using Linux as a desktop but i do have it running as a VM server so i might give that a try a bit later
The funny thing is, its not complicated to do it (apparently) its just no one has really used the protected feature set of the SD standard
Also, (apparently, some SD cards use the protected area to store information other than the encryption key for the whole card, apparently this information might be used in read /write operations on the card, clearing the protected area to remove the SD card lock might have a negative impact on the cards performance.

Interesting. I did a few experiments and a whole heap of reading about this yesterday (Osx doesnt recognise the card either btw):
The card became locked during the update process from 7712 to 7720 during one of the many hard resets i did whilst installing the cabs (the sd fix cab was the last cab i installed). My mistake was not bothering to change the language from its default (English USA to English UK) so it would appear the card is also not only locked to a particular device but its language also.
One could test this by inserting the card, hard resetting and choosing USA as its language, however, it took 4 hours to get the device working to 7720 so im not doing that just yet; so i tried something else.
I put the encrypted card into my hd2, entered magldr and cleared the partition using services. I then entered usb mass storage and connected the device to my PC (win 7 x64). Whilst the card was not recognised in "my computer", if you look in camera&scanners in control panel, you will see magldr is recognised as a mass storage device but the device drivers for this fail to install properly. This is probably due to the "unknown" partition taking up the full capacity of the micro sd card and why it is not recognised by the PC hence it cannot be used for storage.
Unfortunately this also means no partition software will recognise the card, nor is it recognised in any digi camera, even after allegedly clearing the partitions via magldr.
I then had a thought would a nokia emulator work in unlocking the card? to which i havent researched any further as yet.
**EDIT** Apparently someone has decrypted and formatted a card using Ubuntu, im off to download and try it
**EDIT 2** not having much luck with ubuntu either, card not recognised........

same here, ubuntu disk manager (11.04 32-bit) shows sd card but 2.2 TB and can't format the drive or volume (i tried the same to clear mbr using magldr), ubuntu is not working

WEll, they havent been much further use, all they say is that is perfectly possible to do with software, the APIs have been there for years, its just that no one has ever really paid much attention to it, with the exception of Sat-Navs, professional Music gear etc.
Ive not had a chance to play with Linux yet but i would imagin that you need to think lower level than partition / MBR levels
From what i can gather from their cryptic responses is that when a SD card is setup to use the Secure feature, the device creates a key in the secure section, only that device can then access that section, the storage space on the card is then encrypted using that key, there is no way short of cracking the key to get access to either the secure section or the storage section. However, when you use an OS or Utility that makes use of the Secure protected area its possible to clear it, this would clear all the data obviously off the card, even disk analysers wouldnt be able to see it as it would still be encrypted.
What is concerning is that the Manufacturers have grown used to this special area and use it, apparently this area is used for IO operations, (probably some kind of cache or superfetch) this speeds things up by predicting what you are going to access next
What concerning is, if you have a class 10 device that as we all ready know uses methods to speed up sequential speeds to get that class rating, IF we manage to clear that protected area will the card be effected in terms of speed, conversly, could it improve random access speeds (WP7 essential) if its not farting around trying to predict sequential IO ops!

I'm going to try as well. If we can just get a recognition/copy to work, then we can do dual-boot again. There has to be some way to copy the entire partition.

read it again,
note the big "AND"
you can not dual boot Mango 7712/7720 and android on V1
you can not dual boot at all with V2
you cant copy encrypted partitions, it doesnt work that way, its not like making a encrypted folder, its on a much lower level than that, its either encrypted or its not, you either have Mango or you have Nodo AND android
I still cant get the Protected SD formatted, im wondering if its reliant on the card reader supporting those commands.....

Mm the secret I think is gaining access to the hidden part of the card that contains the encryption key. I'm still working on Ubuntu and have a lead to follow up on.
Your right about the droid dual boot, this isn't my intention so others shouldn't get their hopes up ;-)

[Q][HD2][NativeSD] Cannot find external SD in camera app

Hi,
I intended to post this question to the [3.Nov.2012][ROM] NexusHD2-JellyBean-4.1.2-CM10 V1.2 [NativeSD] thread, but not allowed to (http://forum.xda-developers.com/showpost.php?p=32624318)
Can someone help me redirect the question? Thanks!
First thanks for the great ROM, tytung. It looks great and easy to install.
I have a HD2 and wanted to dual boot WP7 and Android. Found this new method NativeSD and decided to try it. But once I installed the ROM (through MAGLDR 1.13 and Recovery 4Ext 2.2.7), everything works fine, except that the camera app (and other apps) says that it cannot find the external SD card to save the pictures. It does not give me options to save on phone. But since both system and data are on external SD, and that partition is treated as /mnt/sdcard0, I am not sure if I am supposed to have an external SD card from the perspective of Android.
Cannot seem to find similar post with this issue, so I must be doing something wrong with partitioning. Could you help??? Thanks so much! I am inches away from having a great Android JellyBean experience on my HD2.
Thanks!!!
-----------------------------------
Details:
4 partitions on my 16GB SD card:
1) FAT32, 3GB (this is the boot partition, where I installed Recovery 4Ext and through it, installed the boot files in /NativeSD)
2) Ext4, 8GB (this is the system/data partition, where installation put all Android files)
3) Ext4, 2GB (this is current empty, reserved for another ROM that requires two partitions)
4) Other, 2GB (this is a WP7 partition)
I formatted these using Mini Partition Tool on Windows (not via Recovery 4Ext)

I think you need to run CHKDSK on your FAT32 partition of the card with fix option, once, using a card reader and computer. Once done, put the card back to your phone and boot to your preferred Native SD rom. Then check whether you applications are able to trace the SD card. Should work, since the same worked for me, when I had a similar issue. Hope that helps.

Hi dheerajk27, thanks for your quick reply. Was wondering
1) should Android JB think that I have an external SD?
2) where will this external SD be mapped to? The Fat32 partition? The same Ext4 partition as system & data?
3) what would chkdsk do? I just want to make sure that it doesn't mess up the Win 7 stuff as well.
Thanks!

Hi braveliquid, welcome to the forum.
Did you set all your partitions as primary using minitool?
1. yes
2. depends photos/music => fat part, apps=>ext part
3. not sure either

Thanks for your reply. Upon multiple trial and error, I found out that the logical partition is the culprit. When I have 3 primary (FAT32, Ext4, Ext4), Android can recognize the ext SD card. However, when I have 3 primary and 1 logical (the Win Phone 7 partition is made logical by windows), then Android does not recognize the ext SD card anymore.
Any thought on how I can resolve this? Or else I will have to keep 2 SD cards, one for WP7, and one for Android. Doable, but a bit of a hassle.
Thanks!

use minitool and set your wp7 partition as primary too.
Problem solved.
you could use two cards, i am at the moment (I keep spare card in a cellotape pocket on inside of battery cover). You can also dual boot without partitioning see http://forum.xda-developers.com/showpost.php?p=34009754&postcount=1126 but only really as a backup phone in case wp7 goes wrong and you are away from pc.

Thanks Robbie. Yes, I have set the WP7 partition as primary and then it works! I am liking the Android experience (have been using iPhone).
Btw, in WP7, it is asking me to update software (I have a very old WP7 installation, migrated to dual boot in early 2011 i think). Can I just upgrade WP7 like normal (i.e. by connecting to Zune)? Or will that destroy MAGLDR? If that won't work, how can I upgrade WP7 to 7.5 or later 7.8? I cannot use Windows Market Place apparently with the old WP7 OS.
Thanks again!

I would just flash one of the new wp7.8 roms, your choice which. Ansar's does not seem to be able to use the new wpbackup app at the moment.
With Hd2o and pdaimatejam you can backup your phone and restore apps sms calls etc. Sooo much better for trying out new roms.
